Application filed January 19, 1886. Serial No. 189,056. (No model.)

To all whom it may concern.-

Be it known that I, FRANCIS M. ROOTS, a citizen of the United States, and a resident of Oonnersville, in the county of Fayette and State of Indiana, have invented certain new and useful Improvements in Portable Forges, of which the following is a specification.

The object of my invention is a portable forge that is simple and inexpensive in construction, that can be readily taken apart and packed in a small space for transportation,

; ters wherever they occur, Figure 1 is a plan through the forge as fitted up for use.

view of the hearth and fire-bed. Fig. 2 is a central longitudinal vertical section taken Fig. 3 is a plan view of the expansion-ring which supports the fire-bed and tuyere. Fig. 4 is a diametrical section of the same, taken through linear a of Fig. 3. Figs. 5 to 10, inclusive, are detail views of the castings for fitting the fireback and hood together, Fig. 5 being a side and Fig. 6 an edge view of the casting which secures the fire-back to the hearth Fig. 7, a side elevation, and Fig. 8 a plan view, of the piece which secures the fire-back and hood together; Fig. 9, a side elevation, and Fig. 10 a plan view, of the *thimble in the top of the hood which receives the smokestack.

The hearth A has a circular opening in it near one end, which has an inwardly-projecting annular flange, a, to support a loose ring, B, which forms part of the hearth. The ring B has a similar flange, 2), extending inward from the lower and inner edge. The fire-bed and tuyere G are supported upon this flange b. The hearth has cast with it downwardly-extending angle-lugs a, in the angles of which the legs E, which are of wrought angle-iron, are secured by screw-bolts a". The lower ends of these legs are heated, then clamped in suitable dies, and upset to form feet 0, which are outwardly-projecting flanges around the lower ends of the legs tofuruish a firm support for the forge. The curb a, which extends around the hearth, has a depression in it opposite the fire-bed,which is closed by a door, (1*, as clearly shown in dotted line, Fig. 2.

Between two of the legs E is secured a crossbrace, G, which is castwith a platform, g, upon which the blower F is supported. The blower is connected to the tuyere by a pipe, H. The bottom of the fire-bed O and the tuyere are constructed like one shown in my application 6 5 filed of even date herewith-that is, having a loosely-fitting removable bottom, consisting of outer ring, I, resting upon the perforated disk J between the air-chamber of the tuyere and fire-bed O. This arrangement is not claimed herein, and no specific description of it is necessary, as any of the well-known forms of fire-bed may be used in my improved forge. The fireback D and hood K are made of sheet metal. The lower end of the back D sets within the circular end of the curb a, and is held firmly in place by the inner curved segment, L, between which and the curb it is clamped by screw-bolts l, which pass through the curb and back and screw into tapped perforations in the segment L. The hood K is united to the back D by a metal segment, M, the lower part of which is in the are of a circle, while the upper edge at each end of the arc flares outwardly to conform to the shape of 8 5 the hood. The back and hood are united through this piece M by means of screws or rivets, as desired. The opening in the top of the hood is fitted with a cast-metal ring or thimble, N, which is shaped exteriorly to 0 snugly fit the upper portion of the hood and 'project through it, to furnish a flange for the smoke-stack to fit over. The sheet-metal back and hood are cutout to the exact size required, and as they are easily bent to shape around 5 the metal pieces M N the back and hood may,

for economy of space, be shipped in the flat shape, as no skill is required to give them the proper form.

The blower F, its drivingwheel H, the :00 standard I, which is secured to the top of the blower, and the brake-arm J, are the same as shown in my application of even date herewith. As they are not claimed separately herein, and as any well-known form of blower may be substituted for it without departing from the main feature of my invention, a specific description is not necessary herein.

\V hat I claim as new, and desire to secure by Letters Patent, is

1. In a portable forge, the combination of 3. In a portable forgo, the combination, as specified, of the hearth A, the fire-bed C, and tuyere with the blower 1 the brace and platform G legs E, and blast-pipe connecting the blower and tuyere, the said blower being mounted upon said platform, and the platform secured by its brace to the legs, the parts being detachable, for the purpose set forth.

4-. A leg for portable forges, consisting of wrought anglc-iron, and having the upset feet or flanges c, substantially as spcelficd.
